Data analysis refers to the domain of fields that investigate the structure of data and use it to identify patterns and possible solutions to problems. Within this domain, data science draws on methodologies from statistics, mathematics, and computer science to both analyze events using data and predict possible outcomes. One important trend within data science is machine learning, which uses algorithmic data inputs and statistical analysis to train computers to output values within a certain range. In this way, machine learning enables practices such as automated decision-making.
